Bathroom in 40x60 Shop Wiring Question

[ryunk]

I plan to provide a single 20A GFCI branch to my single bathroom receptacles and lighting (one receptacle and two light fixtures). I also want to provide this branch power to three receptacle boxes that are in the bathroom walls but facing to the outside of the bathroom (essentially supplying additional receptacles to the shop area).

Is this plan acceptable (within code)?

Yes.. You can always GFI things that do not require it.

With out a doubt i my mind, those added GFCI outlets will pass code inspection.

probably region specific . pretty sure here you need a 15 or 20 amp dedicated circuit for the bathroom outlet .

No. The bathroom requires a dedicated 20A circuit for receptacle outlets. It can be shared among bathrooms if the lighting in the bathrooms is on a separate circuit (so when you blow the breaker in one bath running a hair dryer and four curling irons, the guy in the shower in the other one isn't left in the dark.), but in no case can the circuit serve other areas. If you have only one bathroom on the circuit, the lights can be on it. See 210.11.

That is for a residential bathroom.

Its your shop. Install your circuits as you see fit for your loading/use - primary consideration is to not trip breakers regularly.

Focus on other workmanship details... splices, terminations, sturdy & roomy boxes, etc.

I thought that too, but isn't this shop in a residence (assuming it is), making this a residential bathroom? I bet this is one that will depend on your inspector and how they interpret the code.

What i have found is the if you wire everything up but don't hook it up for lights and such to run on same circuit it will pass without them hooked up so you have a dedicated circuit for the outlets, which after its signed off you can do what you like to it.

 

[Norcal]

Lights and receptacles in a shop should not be on the same circuit(s), just my opinion.

If the shop is attached to the structure then it's considered a residential bathroom.
If it's detached then it wouldn't necessarily be considered residential.
I'd ask your inspection dept.

 

[dcg9381]

The "residential" issue is going to be subjective.
Can you use the same GFI circuit for outside the bath, IMHO yes - subject to someone outside the bath can shut down the bath outlets (which should not include the lighting).

To the guys that say baths cannot share circuits, how about the RV case? GFIs are regularly shared... I'd claim that this is more "residential" than a shop...

The GFCI in a bathroom needs to be a dedicated 20 amp circuit. All the GFCI's inside other bathrooms can share this circuit. So, if this circuit is supplying power to GFCI's in multiple bathrooms, nothing else can be on it. No lighting or fans in the bathrooms, and no receptacles or lighting outside the bathrooms.

But, you can take a dedicated 20 amp circuit and feed a single bathroom, GFCI, lights and fan. But that circuit can not leave that bathroom.

I have run into this on two separate occasions. One, the shop was considered residential and had to have the gfci connected to the bathroom circuit and nothing else. The feeder for that one came from the house service. The other shop was considered commercial, even though it was at a residence, because it had it's own service. It received a gfci that was connected to the same circuit as the other side of the wall. I am willing to bet that nothing has been plugged into it since the inspectors tester eight years ago.

 

[Norcal]

If not considered residential I also see no issue with the GFCI for the bathroom being off the shop circuit, it's really doubtful that the OP is going to be blow drying his hair in there & that is the reason for the requirement.

With that being said, I've got a new home where we've got these dual arc-fault/GFI breakers. They absolutely **** **** ****. We've had to replace many of them with standard arc-fault and then put a GFI in-line in the circuit.
